Dual-socket 1U compute density

The Dell PowerEdge R640 packs two Intel Xeon Gold 6142 processors into a single rack unit, delivering 32 cores and 64 threads at a 2.60 GHz base frequency. It is built for virtualization clusters, high-performance databases and scale-out workloads that demand maximum throughput per rack slot.

Sustained multi-core throughput

With 256 GB of DDR4 2666 MHz registered ECC memory across 24 slots, the system maintains consistent bandwidth for memory-bound applications under continuous load. Dual 750 W platinum power supplies and redundant hot-swap cooling keep both CPUs at their rated turbo frequency without thermal throttling during extended compute runs.

12 Gb/s SAS/SATA storage ceiling

The PERC H730P controller with 2 GB cache supports RAID 0, 1, 5, 6, 10, 50 and 60 across eight 2.5-inch drive bays, limiting array performance to the SAS/SATA interface rather than PCIe-attached flash. Network I/O is bounded by the quad-port daughter card providing two 1 GbE and two 10 Gb SFP+ links.

Questions about this item

How loud and hot does the R640 get with both Xeon Gold 6142 CPUs at full load all day?

Dual 750 W Platinum supplies and redundant hot-swap fans keep the 1U chassis cool; power draw scales with the 2.6 GHz base and 3.7 GHz turbo clocks of the two 16-core processors.

Which drives and cabling must I supply to use the eight 2.5-inch bays?

The H730P controller supports SATA and SAS drives; eight empty trays are included, so you add the 2.5-inch disks and cables you need.

Will my existing DDR4-2666 ECC DIMMs work alongside the installed memory?

Yes, the 24 slots accept registered DDR4 ECC up to 2666 MHz; the system ships with 256 GB in eight 32 GB modules, leaving 16 slots free for matching sticks.
